Choose the points that are collinear.

Find the lines of symmetry for each shape. Select all that apply. A. l B. m C. n D. o

2. Which of the following could be a linear combination of the set {(a, b), (c, d)}? (Circle ALL that apply) a. (3a, 3b) (2a + 2c, b + d) d. (2a-c, 2b-d) b. (2a, b + 2d) C.

Refer to your pictures and pick one pair that you believe are congruent and one pair that you believe are similar based on the copies you have made on the coordinate plane. Using a protractor and a ruler, prove that the pair is congruent and the other pair is similar. Remember, you will need to use the side lengths and the angles measures. Make sure to include the scale factor between your two similar shapes.   Which pictures did you decide were congruent? Provide all of your information and copies of your pictures to prove they are congruent.   Which pictures did you decide were similar? Provide all of your information and copies of your pictures to prove they are similar.   Attach all your evidence.

Directions: For each question, be sure to answer each questions in as much detail as possible in the spaces provided. 1. The city of Petersburg has 12,500 registered voters. There are two candidates for city council in an upcoming election: Brown and Stephens. The day before the election, a telephone poll of 500 randomly selected registered voters was conducted. 207 said they vote for Brown, 249 said they’d vote for Stephens, and 45 was undecided. Describe the population the surveyors are really interested in. Give the sample statistic for the proportion of voters surveyed who said they would vote for Brown. The proportion should be a fraction or decimal, not a percent.

a and b are two points in the third dimension. Write an equation that describes the set of points that are equidistant to a and b. Draw a picture of this set in the case where a = i and b = j.
